All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. On November 26, 2021, the World Health Organization (WHO) indicated a new SARS-CoV-2 variant of concern, which became known as Omicron . Trusted Source There have also been some worries that Omicron can bypass the protection conferred by COVID-19 vaccines. Pfizer maintains that three doses of its mRNA vaccine are able to neutralize Omicron in laboratory experiments and that two doses may still prevent serious illness following infection with this variant. What symptoms does Omicron cause?
The Centers for Disease Control and Prevention (CDC) lists the possible
symptoms of a SARS-CoV-2 infection without specifying a variant. These are: Trusted Source fever or chills cough shortness of breath or difficulty breathing fatigue muscle or body aches headache new loss of taste or smell sore throat congestion or runny nose nausea or vomiting diarrhea
However, the CDC notes this list is not exhaustive, and people might experience different symptoms or combinations of symptoms. Furthermore, anecdotal reports on social media and other platforms claim that more specific combinations of symptoms characterize Omicron infections.
Does it affect the lungs? Medical News Today spoke to Dr. David M. Cutler, a family physician at Saint John’s Physician Partners in Santa Monica, CA, to find out more about doctors’ advice regarding symptoms of an Omicron infection.
Dr. Cutler reiterated that symptoms vary and may not stand out in any particular way, compared to signs of infection with previous variants.
“The variety of symptoms seen with Omicron is the same as with other SARS-CoV-2 variants,” he said. “It seems quite notable that people affected by the same variables may experience quite different symptoms. Some get nasal stuffiness, others headache, sometimes body aches, and others get a sore throat.”
However, he noted, “Serious lung infections appear to be less likely with Omicron than [with] prior variants.”
That may be because, unlike other variants, Omicron preferentially infects the upper respiratory tract. This may also be why it seems to cause milder symptoms, according to WHO Incident Manager Abdi Mahamud.
“We are seeing more and more studies pointing out that Omicron is infecting the upper part of the body. Unlike the other ones, that could cause severe pneumonia,” he says, though cautions that more studies are necessary to confirm this.
Treatment for mild Omicron infection:
What happens if you become infected with the Omicron variant, and symptoms are mild enough not to require hospitalized care? How can you treat a mild infection at home?
“There are no specific home non-prescription drug remedies for preventing or treating [COVID-19],
The best remedies are similar to those you might use to treat mild flu symptoms or a cold:
“Recommended treatment is directed at the symptoms: stay hydrated, rested, and well-nourished. Take acetaminophen or ibuprofen to relieve headache, body aches, or fever. Avoid unproven remedies like hydroxychloroquine, ivermectin, zinc, and vitamin D, which have no known value and can cause adverse effects.”
